Ancient Snakes Had Legs—But Not For Walking

Quote

 

Scientists aren’t sure if snakes evolved on land or in the water, but the recent discovery of a remarkable fossil in Brazil seemed to suggest a terrestrial origin story. Last year, a group of scientists led by Nicholas R. Longrich put out a study arguing that this snake-like creature, named Tetrapdophis amplectus, was a terrestrial animal.
 
But a new study published in Cretaceous Research challenges this assumption. The authors argue that T. amplectus was more closely related to aquatic lizards, and that these snake-like forebears evolved their long bodies for eel-like swimming.
